The Learning Goal for this Assignment is<br />

Relate properties of atoms and their position in the periodic table to the arrangement of their electrons.<br />

Alkali Metals<br />

The alkali metals are all shiny, soft, highly reactive metals at standard temperature and pressure and readily lose their outermost electron to form cat<br />

with charge +1. Can be easily cut with a knife, due to their softness, which exposes a shiny surface which is quickly tarnished due to oxidation.They<br />

highly reactive, so they must be stored in oils to prevent from reacting with air. They are also only found naturally in salts, and never the free elemen<br />

Alkali Earth Metals<br />

Alkali earth metals all share similar properties, in that they are shiny, silvery-white, and are moderately-reactive metals at standard temperatures.<br />

They have a common s-electron shell, which is full, and readily lose their valence electrons to form cations with charge +2. All of the discovered<br />

alkali earth metals can be found in nature<br />

Transitional Metals<br />

Transition metals are defined as: an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete d sub-shell, In general,<br />

transition metals possess a high density and high melting points and boiling points.<br />

Inter Transitional Metals<br />

Consistent of the actinide and lanthanide metals, they are very similar, and the actinides are all radioactive.They have three incomplete outermost electron shells<br />

and are all metals. They can be in some cases quite malleable and ductile. They do not occur in nature (except for the lanthanides, thorium and uranium) and are<br />

highly unstable.<br />

Metals<br />

A material (an element, compound, or alloy) that is typically hard, opaque, shiny, and has good electrical and thermal conductivity.<br />

Metals are generally malleable — that is, they can be hammered or pressed permanently out of shape without breaking or cracking — as well as<br />

fusible (able to be fused or melted) and ductile (able to be drawn out into a thin wire).<br />

Metalloids<br />

A metalloid is any chemical element which has properties in between those of metals and nonmetals, or that has a mixture of them. There is neither a standard<br />

definition of a metalloid nor complete agreement on the elements appropriately classified as such. Despite the lack of specificity, the term remains in use in the<br />

literature of chemistry. Typical metalloids have a metallic appearance, but they are brittle and only fair conductors of electricity. Chemically, they behave mostly as<br />

nonmetals. They can form alloys with metals. Most of their other physical and chemical properties are intermediate in nature. Metalloids are usually too brittle to have<br />

any structural uses.<br />

Non Metals<br />

In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks metallic attributes. Physically, nonmetals tend to be highly volatile (easily vaporized),<br />

have low elasticity, and are good insulators of heat and electricity; chemically, they tend to have high ionization energy and electronegativity values, and gain or share<br />

electrons when they react with other elements or compounds. Moving rightward across the standard form of the periodic table, nonmetals adopt structures that have<br />

progressively fewer nearest neighbours.<br />

Noble Gases<br />

The noble gases make a group of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very<br />

low chemical reactivity. Noble gases are typically highly unreactive except when under particular extreme conditions. The inertness of noble gases makes them very<br />

suitable in applications where reactions are not wanted.<br />
